1.用來處理Content-Type: 為 application/x-www-form-urlencoded編碼的內容。(Http協議中,如果不指定Content-Type,則默認傳遞的參數就是application/x-www-form-urlencoded類型) @RequestParam可以接受簡單類型的屬性,也可以接受對象類型。 2.用來處理 multipart/form-data (表單上傳的)
如何使用@RequestParam 接受JSON的字符串
前端代碼
const message = {
"data": {
"userInfo": "2804951212",
"offerId": offerId,
"action": "distribution",
"categoryNav": categoryNav
},
"gmtBorn": time,
"msgId": time,
"type": "PRODUCT_COLLECTION",
"userInfo": "chrome"
};
$.ajax({
contentType :'application/x-www-form-urlencoded',
type:'post',
url: baseUrl+'/ali-receive',
data:"message="+JSON.stringify(message)
});
@PostMapping("/ali-receive")
public void aliReceive(@RequestParam("message") String message) {
ReceiveLog receiveLog = JSON.parseObject(message, ReceiveLog.class);
}
@RequestBody
一般用來處理 Content-Type: 為application/json
